Answer:
When looking at this model, and asking yourself the question, is PRB congruent to QSB? PRB is in fact congruent to QSB. Congruent means that two figures have the same shape/size, no matter if it's mirrioring or not it is congruent. In this image, PRB is one shape, and QSB is another. They have the exact same points and they're also the same shape, but one is flipped the right side up. It was also stated PQ and RS bisect eachother at point B, <p is congruent to <Q, and <R is congruent to <S proving all these connections make this figure conguent.
Step-by-step explanation:
Since A‘(-1,1) is on the line y=-x, reflecting it about the line doesn't change its coordinate, so A's coordinate is (-1,1). Reflecting B'(-2,1) about y=-x switches both the sign and the number of x and y, so B=(-1,2), and C'(-1,0) becomes C(0,1). Drawing out the graph with the points and the line helps.
58 degrees bra cause the arc is 58 degrees and due to congruent angles x is also 58 degrees
The product has decreased by 80 %
<em><u>Solution:</u></em>
The product of the original numbers: xy
One number is decreased by 75 %
Let x be the number decreased by 75 %
new number = x - 75 % of x
Another number is decreased by 20 %
Let y be the number decreased by 20 %
new number = y - 20 % of y
<em><u>Now the product is given as:</u></em>
<em><u>Now we have to find the percent decreased</u></em>
Subtract new product and original product and then divide by original product . Multiply the result by 100 to get percentage
Here negative sign denotes decrease
Thus the product has decreased by 80 %
D) There is no association between commuting preferences and gender.
